There are six small and very individual districts there: Baroche, Haute Ajoie (with the Bure plateau), Basse Allaine, Vendline, Coeuvate and at the heart of Ajoie, the Porrentruy district. These are tiny districts with their own features and their own traditions, all of which help to enrich the culture found in Ajoie.

Summer

The landscape of Ajoie, defined by fertile soil and vineyards, is especially popular with hikers and bicyclists. Or even multiple-day rides with a horse-drawn carriage let you extensively explore the area. Known also as the “vineyard of the Jura Mountains,” the area is also home to the rare trees of the Damassine plum (used for brandy distillation).
